Abstract: Batteries are already and will continue to be the most important energy storage systems for operating portable electronic devices and electric vehicles as well as for stationary energy storage in power grids. Lithium-ion batteries (LIBs), which dominate the market for portabledevices and electric vehicles, have been optimized for higher energy density over the past 30 years. However, the physicochemical limit of LIBs based on the state-of-the-art Li[NixCoyMn1–x–y]O2 (NCM)/carbon chemistry has almost been reached, requiring thedevelopment of new battery technologies. To meet the future requirements, a further battery improvement is needed in terms of a higher energy density, a longer cycle life, and higher safety levels. All-solid-state batteries (ASBs), including ceramic ASBs with garnet electrolytes, areconsidered as one of the promising next generation battery technologies, so the further development and optimization of the garnet-type ASBs is the focus of this thesis. Unlike conventional LIBs, garnet-based ASBs use Li6.45Al0.05La3Zr1.6Ta0.4O12 (LLZO:Ta) garnet asseparator and solid-state electrolyte (SSE). Due to the ceramic nature of the SSE, the garnetbased SSEs are nonflammable and offer a higher safety than LIBs based on liquid, organic electrolytes...
